RUNNING GEAR.

AS S. VVArsoN, a and resident in the county of Milwaukee have invented new in Runnmg Gears,

to conveying strucy to the running gear for. positively driving the propelling the supportlng rails by structure along means of a prope provide a simple of supporting rail and the pins ing gear The principal ob ect and rack.

of the invention is to and compact combination pin rack in which forming the rack are carried by the supporting rail and are so constructed as to reduce to a minimum the liability 0t clogging the rack, and to moval of snow, lee,

permit the ready redlrt or other foreign matter from the vicinity of the rack.

With the above an the invention conslsts 1 and the several 'l'eatures d other objects in view n the construction thereof hereinafter described and all equivalents.

A motor is mounted on motor, gearing 9 drives. ries bevel gears gears 12 on transm shaft 13 carrying a gear with a gear nailed in members 18.

side by plates Q0 extending along the rails and positioned to overlap the rail joints. These plates '20 are disposed in upright po, sit-ion between the head and base of the rail and are preferably secured to the rail by the elements 'lorniingthe pin rack.

The elements itoriining the pin rack preferably in the form of bolts or pins having round heads 22 and havi g threaded shanks passing through alinet. openings in the plates 20 and the web oi? the rail. These bolts 21 are clamped in position with their heads abutting against the ex posed sides of the plates 20 bynuts 23 abutting against washers 24:. These bolts also serve to clamp the plates 20 to the rails. The plates 20 in addition to forming tie plates between. the sections ofthe supporting rail 7 also form a straight side for the supporting rail from which the rack pins project and as the heads of such pins are not confined and are elevated above the roadbed and spaced from each other, the liability of cloggingthe rack is reduced to a minimum. Furthermore, since the rack is fully exposed any foreign matter tending to collect in the region of the rack may be readily removed. With this construction the rail and rack are made continuous, that is, the rail with its pin rack extends the length of the area over which the conveying structure operates. llhe weight of the conveying structure is taken by the supporting and guide rails 7 so that the rack pins, successively engaged by the propelling wheels 19 of each truck to positively propel the structure along its track, are relieved oil any strain occasioned by this weight.

I desire it to be umflerstood that this invention is not to be limited to any specific form or arrangementoil? parts except in so tar as such limitations are specified in. the claims.

What I claim as my invention is:

1. Running-gear for conveying structures coinprisinga truck, a rail, supporting and guide wheels for said truck and running on said rail, spaced pins carried by the rail and projecting therefrom to form a pin rack, and a propelling wheel on the truck engageable with said rack.

Running-gear for conveying structures comprising a truck, a rail, supporting and guide Wheels for said truck and running on said rail, and horizontally disposed spaced pins passing through and clzn'nped to the rail and projecting therefrom to form a pin rack, and a propelling; wheel on the truck engageable with said rack.

Running-gear for conveying structures comprising a truck. a rail, supporting and guide Wheels for said truck and running onv said rail, plates disposed alongside of said rail, transversely d'sposed spaced pins passingthrough said plates and rail and joining the plates to the rail and having headed proections forming a pin rack, and a propelling Wheel on the truck engageable with said rack.

4-. Running-gear for conveying structures comprising a. truck, a rail, supporting and guide Wheels for said truck and running on said rail, spaced pins having heads projecting from the rail to form a pin rack, thread ed shanks passing through the rail, nuts on said shanks clamping said pins in position,

mnmeo and a inopolling wheel on the truck cng'ago able with said rack.

5. Running-gear for conveying structu es comprising a truck, a sectional rail, suppo ting and guide wheels for said. truck and running on said rail, plates joining the sections of the rail together and disposed against one side of the rail, transversely disposed spaced pins passing through said plates and rail and joining the plates to the rail, said pins having headed projections forming a pin raclg-and a propelling Wheel on the truck on gageahle with said rack.

Running-gear "for conveying structures comprising a truclga sectional rail, supporting and guide wheels for said truck and running on said rail,n1eans for joining the sections of the rail spaced pins having said plates to form polling Wheel on the heads projecting from a pin rack, and a pro A truck engageahle with said rack.

In testimony whereof, I aflix my signature.
